AUTOMATIC TELEGRAPH.

SPECIFICATION forming part of Letterslatent No. 676,854, dated June 18, 1901.

To all whom it may concern.-

Be it known'that I, HARRY SHOEMAKER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,'have inventedcertain new and useful Improvements in Automatic Telegraphs, of which the following is a specification.

- This invention relates to improvements in automatic telegraphs and the main object of the invention is the provision of an automatic telegraph which will transmit and receive messages in very rapid succession and which is very simple and practical in construction and use.

To attain the desired objects,the invention consists of an automatic telegraph embodying novel features of construction and combination of parts, substantially as disclosed herein.

In the drawings, Figure 1 is a diagrammatical View of the entire system. Fig. 2 is a side elevation of the transmitting mechanism. Fig. 3 is a side elevation of the central magnets, and Fig. 4 is an end view of the receiving and printing mechanism.

Referring to the drawings, the numeral 1 designates the base, upon which is mounted a clock mechanism 2 or any suitable motive power. Operated by this mechanism are the paper-feeding rollers 3, which are adapted to pass the perforated oiled paper 4, provided with dash-spaces 5 and dotrspaces 5 over the surfaces or plates 6 and 6, mounted upon the base. Connected to the post or block 7 are the plates 8 and 8, providedwith the downwardly-extending pointed ends 9 and the extensions 10, which are adapted to contact the points 10 to make a circuit when the 4 When the plate 8' makes a circuit,it is through points 9 enter the perforations in the paper.

the plate, the block 7, the wire 11, the electromagnet 12, the wire 13, its batteries 14, and wire leading to one of the contact-points 10 and when the plate 8 contacts the other of the points 10 a reverse-current is sent through the batteries 15, wire 13, electromagnet 12, wire 11, block 7, and the plate 8. The wire 11 is connected to and always in circuit with the post or block 7, so that a circuit is always made with said wire whether '25 26 when the apparatus is passive.

the plate 8 or 8 makes a circuit. This electromagnet 12 consists of the two coils 16, connected by the yoke 17. It also has the two cores 18 and 18", the core 18 being provided with a channel 18 therethrough. Mounted upon the base with the magnets are the vertical standards 19, which are the coils of a permanent magnet and between which is suspended the vibrating plate or strip 20, composed of the spring 20 the magnetic strip 20", and the non-magnetic strip 20. I make this strip 20 of the three different partsin order that the spring 2O will allow it to be vibrated properly, that the magnetic strip 20 can be readily attracted by the cores 18 and 18 and that the non-magnetic strip 20' cannot be affected by the magnetic standards or poles 19, between which this strip is suspended. Connected to the magnetic strip 20 is the wire 21, which passes through the hollow core of the magnet and is connected with the suspended disk 22, which is adapted to contact the posts 23, 24, 25, and 26, the posts 23 and 24 being contacted when the core 18 is mag netized in one direction, thus closing a circuit through the wire 27, batteries 27, wire 28, through the magnets, and the wire 28, to the disk 22, thus making a reverse-circuit in the magnets. At the same time another circuit is made through the post 23, wire 29, which connects with the magnet 30, a wire 31, battery 32 completing the circuit through the adjustable spring 32, wire 21, and disk '22, connected to the end of the wire 21, as

strong enough to hold the disk 22 about midway between the two pairs of posts 23 24 and This circuit operates the magnet 30, which attracts the armature 33, held normally in a vertical position by the two springs 34, toward it, thus turning the disk or shutter 35, provided with the dot-apertu re 36 and the dash-slot 37. This disk is mounted upon the armature-shaft 38. \Vhen the disk22 contacts the posts 25 and 26, two circuits are formed, one through the post 26, the wire 39, batteries 39, wire 27, wire 28, the magnets, the wire 28, and disk 22, and another circuit through the post 25, wire 40, magnet 41, and thence through the wire 42 to the batteries 32 and the spring 32, wire 21, disk 22, this circuit pulling the armature toward the other magnet to bring the shutter improper position to print a dash. This shutter is mounted behind the plate or guide 42, provided with the opening 43, which allows rays of light from a lamp 44 and lens 45 to be concentrated upon the opening of the disk as it is moved in front of the opening 43 to expose or print a dot or dash upon the sensitized film or paper 46, mounted upon the rollers 47 From this description, taken in connection with the drawings, the operation of my automatic telegraph is readily understood; but, briefly stated, it is as follows: The oiled paper is perforated, as desired, with the dot and dash spaces upon their respective sides. The clock mechanism is setin operation, the paper being fed between the rolls over the plates below the points 8 and 8. When the perforations pass below their respective points, the extensions 10 of the 'plates form a circuit with the points 10 -that is, one at a time. These circuits operate the magnets 12, which attract the plate 20 in this proper direction, this plate making proper circuits with the short reversing-circuit, which helps tear down the magnets and makes the action rapid, and the magnets 30 and 41, which become magnetized and attract the armature carrying the disk 35,causing it to be oscillated in the proper direction to present the dot or dash aperture of the disk, so that the outline thereof is transferred to the sensitized film or paper, which is afterward developed to secure the message.

Thus it will be seen that I produce a very simple and thorough automatic telegraph, which can send messages in a very rapid manner and which .is therefore very useful and practical.
